Creating a Machine Through DigitalOcean Droplet

Creating a DigitalOcean Droplet is the simplest and most fool-proof way of setting up a more secure and private website or application. Choosing an OS and Size will depend upon your needs. There are many Operating systems that you can choose from including Ubuntu, Fedora, Debian, and FreeBSD depending on your needs and preferences. After selecting an OS and size from the list, you need to select a data center and the following configuration options. You will also need to select the SSH key (strongly advisable) and the monitoring option. Once all the required options are configured, you can proceed to creating the Droplet.

Once your Droplet is created, you’ll be able to access it over SSH. This requires the SSH key you set up during the Droplet’s creation. Alternatively, you can utilize DigitalOcean’s cloud console to access the Droplet, configure users, and access the machine. DigitalOcean provides a tutorial on the cloud console that will allow you to access the Droplet and perform basic, non-destructive administrative tasks.

Setting Up Node Express with Nginx

The process of setting up Node Express with Nginx on a DigitalOcean Droplet is fairly simple. First, you’ll need to install the Node Express, the Node version manager (nvm) and the Nginx web server. Nvm makes it easy to manage and switch between different versions of Node. This can be done by running the following commands in the terminal:

  • curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.30.2/install.sh | bash
  • nvm install 0.12
  • nvm use 0.12
  • npm install -g express-generator
  • npm install -g nginx

Once the installation is complete, you can create an Express application by running the following command:

  • express YourAppName

This will create a folder with the same name as your application. The folder should contain all the necessary files for running a Node Express application. You can then move into the folder and configure the Nginx configuration file. This can be done with the following command:

  • sudo nano /etc/nginx/sites-available/default

You should then configure the server and locations settings in the file. A sample configuration would look like this:

  • server {
  •     server_name example.com;
  •     location / {
  •         root /var/www/YourAppName/public;
  •         proxy_pass http://127.0.0.1:3000;
  •         proxy_http_version 1.1;
  •         proxy_set_header Upgrade $http_upgrade;
  •         proxy_set_header Connection ‘upgrade’;
  •         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  •         proxy_cache_bypass $http_upgrade;
  •     }
  • }

And then save and close the file. Finally, you need to restart nginx and start the Node Express application:

  • sudo service nginx restart
  • cd YourAppName
  • node server.js
    • MongoDB Installation and Setup

      MongoDB is an open source database that can be used to store and manage data. To install and configure MongoDB, you need to download and install the software from the official website. The installation and setup process is straightforward and requires the creation of a user and a database. Once the initial setup is complete, you need to populate the database with data. The process of populating the database depends on the application and database structure. MongoDB offers comprehensive documentation on the installation and setup process.

      Once the database is populated, you will need to configure an application to use the database. MongoDB also provides extensive documentation on how to access and use the database from various applications. An application written in Node Express will use the Mongoose library to access the MongoDB database.

      Securing With SSL and Firewall

      Securing a website and application is always the first priority. Securing the website with an SSL certificate is essential to ensure sensitive information is not exposed. The safest way to get an SSL certificate is to use a reputable provider.

      In addition to an SSL certificate, it also important to secure the server and website with a firewall. A firewall is a basic security measure to protect the server from malicious attacks. DigitalOcean provides a built-in firewall feature that can be used to configure the firewall rules for the server and website. This can be done by selecting the Firewall option in the DigitalOcean dashboard.

      Optimizing Performance

      In order to get optimum performance from your website or application, it is important to optimize the performance for the particular platform. This can be done by keeping the application lightweight, utilizing caching technologies, and using CDNs (Content Delivery Network).

      Keeping the application lightweight can be done by utilizing the latest development frameworks such as Node Express and MongoDB. These frameworks are fast, efficient, and secure. Utilizing basic caching strategies can also help to improve performance. Caching strategies, such as minifying JavaScript and CSS files, can help the browser to cache and load the files more quickly. Lastly, utilizing a CDN can also help to improve performance by delivering content from multiple servers worldwide.
